Description Joseph S. Myers 2013-10-18 20:29:21 UTC 
The powerpc port should have an insn pattern for copysigntf3 for soft-float and e500v1; right now, the complex multiplication/division in libgcc ends up with an undefined reference to copysignl in those configurations.  This doesn't generally cause problems for glibc users - glibc has copysignl in libc as well as libm - but can trip up users of other C libraries.
